Portable telephone capable of increasing facility of operation

ABSTRACT

In a portable telephone which transmits and receives data having at least one of a voice signal and an image datum which are radio signals, the controlling device controls an amplifier so that a user can hear, at a first state that an ear is not near to a speaker, the voice from the speaker when the data from a base station includes a discrimination datum which represents the image datum. The controlling device controls the amplifier so that the user can hear, at a second state that the ear is near to the speaker, the voice from the speaker when the data from the base station does not include the discrimination datum which represents the image datum.

BACKGROUND OF THE INVENTION

This invention relates to a portable telephone which transmits datahaving at least one of a voice signal and an image datum which are radiosignals to a communicating device through a base station, and whichreceives the data having at least one of the voice signal and the imagedatum from the communicating device through the base station.

Recently, image transmission becomes important in accordance withdevelopment of communication technology. Therefore, various terminaldevices which can execute image transmission are provided. In addition,a conventional portable telephone of the type comprises a body, anantenna, an operation device, a speaker, a display device, a microphone,a camera, a transmitting and receiving device, a controlling device, andamplifiers. The antenna is attached to the body. The operation device,the speaker, the display device, the microphone, and the camera aremounted on the body.

Also, according to development of communication technology, facsimileservice that where a facsimile device requests and receives a necessarydatum is executed. Also, push-phone service such as preengagementpre-engagement of an airline ticket and remainder inquiry of a bankdeposit is are executed. In these services, a user transmits, byoperating ten keys of a telephone, datum of a predetermined telephonenumber to one of these service systems to connect the telephone to theone of these service systems. Thereafter, the user operates the ten keysof the telephone, in response to a guidance message, to transmit data ofsuch as a number (BOX number) representing a datum which is needs neededfor a DTMF signal, an account number, and a preengagement time. Thereby,the user can obtain data.

However, in the portable telephone, there is a problem that facility ofoperation is wrong. This is because, since the handset of the portabletelephone is integrated with ten keys, the user cups the portabletelephone to the user's ear when the user hear hears the guidancemessages and the user disconnect removes the portable telephone from theuser's ear when the user operates the ten keys. Also, in the portabletelephone, there is another problem that the user is hardly able to heara voice from the speaker when the user disconnect removes the portabletelephone from the user's ear to operate the ten keys. In addition, inthe portable telephone, there is still another problem that it is needsto set, by such as by a switching circuit, a hands free mode in casethat the user executes conservation while the user see sees image datawhich is displayed.

The antenna 2supplies the receiving data to the transmitting and receiving device 8.The transmitting and receiving device 8 receives the receiving data fromthe antenna 1 and supplies the receiving data to the controlling device9. The operation device 3 supplies operation signals to the controllingdevice 9.

The controlling device 9 receives the receiving data having at least oneof the voice signal and the image datum from the transmitting andreceiving device 8 in this time, the controlling device 9 supplies thevoice signal to the speaker 4 through the amplifier 10 and supplies theimage datum to the display device 5. The amplifier 10 receives the voicesignal from the controlling device 9 and amplifies the voice signal toproduce an amplified voice signal. The amplifier 10 supplies theamplified voice signal to the speaker 4. The speaker 4 receives theamplified voice signal from the amplifier 10 to output a voice.

The controlling device 9 controls the amplifier 10 in response to adiscrimination datum which represents one kind of the voice signal andthe image datum and which is included in a call setting datum signalwhich is sent, in a an establishment time of a data link, from the basestation.

The controlling device 9 controls the amplifier 10 so that a user canhear, at a first state that where an ear is not near to the speaker 4,the voice from the speaker 4 when the data signal from the base stationincludes the discrimination datum which represents the image datum,namely, in a hands free mode or in a voice enlarging mode. Also, thecontrolling device 9 controls the amplifier 10 so that the user canhear, at a second state that where the ear is near to the speaker 4, thevoice from the speaker 4 when the data signal from the base station doesnot include the discrimination datum which represents the image datum,namely, in a voice normal mode. The discrimination datum is defined bytransmission capacity, the transmission capacity represents a datatransfer capacity and a data transfer velocity. The display device 5receives the image datum from the controlling device 9 and displays theimage datum.

The microphone 6 receives a transmitting voice to produce and supply ananalog transmitting voice signal to the amplifier 11. The amplifier 11receives the analog transmitting voice signal and amplifies the analogtransmitting voice signal to produce and supply a amplified transmittingvoice signal to the controlling device 9. The controlling device 9controls the amplifier 11. The controlling device 9 receives theamplified transmitting voice signal. The controlling device 9 encodesthe amplified transmitting voice signal to produce an encodedtransmitting voice signal. In addition, the controlling device 9modulates, by frequency modulation, the encoded transmitting voicesignal to produce a modulated transmitting voice signal.

The controlling device 9 supplies the modulated transmitting voicesignal, as the transmitting voice signal to the transmitting andreceiving device 8. The transmitting and receiving device 8 receives thetransmitting voice signal and supplies the transmitting voice signal tothe antenna 2. The antenna 2 receives the transmitting voice signal andtransmits the transmitting voice signal, as the voice signal, to thebase station.

The camera 7 produces a transmitting image datum to supply thetransmitting image signal to the controlling device 9. The controllingdevice 9 receives the transmitting image datum. The controlling device 9encodes the transmitting image signal to produce an encoded transmittingimage datum. In addition, the controlling device 9 modulates, byfrequency modulation, the encoded transmitting image datum to produce amodulated transmitting image datum.

The controlling device 9 supplies the modulated transmitting imagedatum, as the transmitting image datum to the transmitting and receivingdevice 8. The transmitting and receiving device 8 receives thetransmitting image datum and supplies the transmitting image datum tothe antenna 2. The antenna 2 receives the transmitting image datum andtransmits the transmitting image datum, as the image datum, to the basestation.

Referring to FIG. 3, the controlling device 9 comprises a maincontrolling section 12, a substitute controlling section 13, and abaseband section 14. The substitute controlling section 13 chieflyexecutes monitor of a power supply voltage, monitor of installation of abattery charger, monitor of keyed input and reset control of a powersupply of the main controlling section 12. The substitute controllingsection 13 is implemented by a substitute microcomputer which has ROMsand RAMs. The substitute microcomputer is operated by a main systemclock signal having 2.45 MHz and a substitute system clock signal having32.0 KHz. Initially, the substitute microcomputer is operated by themain system clock signal having 2.45 MHz. After the substitute systemclock signal has the stable 32.0 KHz, the substitute microcomputer isoperated by the substitute system clock signal instead of the mainsystem clock signal and the substitute microcomputer stops to producethe main system clock signal. Thereby, it is possible to decreaseconsumption electric power.

The main controlling section 12 is implemented by a main microcomputer14, a flash ROM 15 16, a SRAM 16 15, a an EEPROM 17, and theseperipheral circuits. The main microcomputer executes such as , forexample, control of the transmitting and receiving device 8, control ofthe speaker 4, control of the amplifier 10, control of the microphone 6,control of the amplifier 11, control of the display device 5, andmonitor of keyed input through the substitute controlling section 13.The main microcomputer 14 has such as , for example, input and outputterminals, serial interfaces, a timer, and an interrupt controller. Themain computer 14 is operated by a clock signal having 16 MHz. The mainmicrocomputer 14 controls parts of the portable telephone. A program ofthe flash ROM 15 16 is able to be rewritten by an outside device throughan outside interface connector.

The baseband section 15 18 is implemented by such as , for example, amodulating and demodulating section, a channel codec section, a radiocontrolling section, and a voice processing section. The basebandsection 15 18 receives the amplified transmitting voice signal from themicrophone 6 through the amplifier 11 and encodes, the PCM and ADPCM,the amplified transmitting voice signal to produce a an encoded voicesignal. The channel codec section decodes the encoded voice signal toproduce and supply the transmitting voice signal to the transmitting andreceiving device 8.

Also, the baseband section 15 18 receives the receiving data having atleast one of the an image datum and the a voice signal. When thebaseband section 15 18 receives the voice signal, the baseband section14 18 demodulates the voice signal to produce a demodulated voice signaland encodes decodes, by ADPCM and PCM, the demodulated voice signal toproduce an encoded a decoded voice signal. The baseband section 15 18supplies the encoded decoded voice signal, as a voice signal, to thespeaker 4 through the amplifier 10. At this time, the controlling device9 controls the amplifier 10 so that the user can hear, at the firststate that the ear is not near to the speaker 4, the voice from thespeaker 4 when the data call setting signal from the base stationincludes the discrimination datum which represents the image datum,namely, in the hands free mode or in the voice enlarging mode. Also, thecontrolling device 9 controls the amplifier 10 so that the user canhear, at the second state that where the ear is near to the speaker 4,the voice from the speaker 4 when the data signal from the base stationdoes not include the discrimination datum which represents the imagedatum, in the voice normal mode.

Referring to FIG. 4, an operation of the portable telephone will bedescribed in detail. The portable telephone transmits, at anestablishment time of a data link between the base station, the datahaving at least one of both of the voice signal and the image datum andthe discrimination datum which is defined by transmission capacity. Thetransmission capacity is included in a call setting datum. Thetransmission capacity represents the data transfer capacity and the datatransfer velocity.

The portable telephone transmits, as the octet 3 of the call settingdatum, the data transfer capacity. Also, the portable telephonetransmits, as the octet 4 of the call setting datum, the data transfervelocity. For example, in the data transfer capacity which istransferred by the octet 3, bit “00000” represents voice, bit “01000”represents data of 32K, bit “01001” represents data of 64K, bit “10000”represents audio of 3.1K, and other bits represent data transfercapacities which are predetermined. For example, in the data transfervelocity which is transferred by the octet 4, but “00111” representstransfer velocity of 8 kbit/s, bit “01010” represents transfer velocityof 16 kbit/s, bit “01100” represents transfer velocity of 32 kbit/s, bit“10000” represents transfer velocity of 64 kbit/s, and other bitsrepresent data transfer velocities which are predetermined.

As shown in FIG. 4, when the portable telephone receives a call from thebase station, the portable telephone transmits a demand of establishmentof link channel to the base station. When the base station receives thedemand of establishment of link channel, the base station allocates achannel, as an allocated channel. The base station transmits datum ofthe allocated channel to the portable telephone. The portable telephonetransmits a synchronous bust signal to the base station. The basestation transmits another synchronous bust signal to the portabletelephone. Next, the portable telephone transmits command of SABM (SetAsynchronous Balanced Mode) to the base station. When the base stationreceives the command of SABM, the base station transmits response of UA(Unnumbered Acknowledge) to the portable telephone.

When the portable telephone receives the response of UA, the portabletelephone transmits a call-accepted signal to the base station. When thebase station receives the call-accepted signal, the base stationtransmits a call setting signal, which includes the transmissioncapacity, to the portable telephone. When the portable telephonereceives call setting signal, the portable telephone transmits a callsetting-accepted signal to the base station. Also, the portabletelephone transmits the call setting datum which includes thetransmission capacity to the base station. When the base stationreceives the call setting datum, the base station transmits a callsetting-accepted signal to the portable telephone.

Referring to FIG. 5, a receiving operation of the portable telephonewill be described in detail. At a step S1, the portable telephone judgeswhether or not the portable telephone receives the data from the basestation. When the portable telephone receives the data, at a step S2,the portable telephone judges whether or not the data call settingsignal includes the discrimination datum which represents the imagedatum. When the data signal includes the discrimination datum whichrepresents the image datum, at a step S3, the portable telephone setsthe voice enlarging mode, namely, the hands free mode. The voiceenlarging mode represents a mode that the controlling device 9 controlsthe amplifier 10 so that the user can hear, at the first state thatwhere the ear is not near to the speaker 4, voice from the speaker 4.

At the step S2, when the data signal does not include the discriminationdatum which represents the image datum, at a step S4, the portabletelephone sets the voice normal mode. The voice normal mode represents amode that he the controlling device 9 controls the amplifier 10 so thatthe user can hear, at the second state that where the ear is near to thespeaker 4, the voice from the speaker 4. A step S5 follows the steps S3and S4 to judge, by the portable telephone, whether or not a receivingoperation is ended. When the receiving operation is not ended, the stepS5 returns to the step S2.

Referring to FIGS. 6 and 7, the description will proceed to a portabletelephone according to a second embodiment of this invention. Similarparts are designated by like reference numerals.

The portable telephone comprises the body 1, the antenna 2, theoperation device 3, the speaker 4, the display device 5, the microphone6, the camera 7, the transmitting and receiving device 8, thecontrolling device 9, the amplifiers 10 and 11, a switching circuit 19,and another speaker 20. The switching circuit 19 is connected to thecontrolling device 9 and to the speakers 4 and 20.

The speaker 4 outputs a first voice when the speaker 4 is supplied withthe amplified voice signal from the amplifier 10 so that the user canhear, at the first state that where the ear is not near to the speaker4, the first voice from the speaker 4 when the data call setting signalfrom the base station includes the discrimination datum which representsthe image datum, namely, in the voice enlarging mode. The speaker 20outputs a second voice when the speaker 20 is supplied with the voicesignal form from the controlling device 9 so that the user can hear, atthe second state that where the ear is near to the speaker 20, thesecond voice from the speaker 20 when the data signal from the basestation does not include the discrimination datum which represents theimage datum, namely, in the voice normal mode.

The switching circuit 19 selectively supplies, in response to a firstcontrol signal and a second control signal, the voice signal to theamplifier 10 (the speaker 4) and the speaker 20. The controlling deviceproduces and supplies the first control signal to the switching circuit19 when the data signal from the base station includes thediscrimination datum which represents the image datum. Also, thecontrolling device 9 produces and supplies the second control signal tothe switching circuit 19 when the data signal from the base station doesnot include the discrimination datum which represents the image datum.
